1. Because the phrase “substantially limits” appears in the Act in the present indicative verb form, we think the language is properly read as requiring that a person be presently –not potentially or hypothetically–substantially limited in order to demonstrate a disability. A “disability” exists only where an impairment “ substantially limits ” a major life activity, not where it “might,” “could,” or “would” be substantially limiting if mitigating measures were not taken. A person whose physical or mental impairment is corrected by medication or other measures does not have an impairment that presently “ substantially limits” a major life activity. To be sure, a person whose physical or mental impairment is corrected by mitigating measures still has an impairment, but if the impairment is corrected it does not “ substantially limi[t]” a major life activity. Sutton Decision: Disability Definition --- Present substantial limitation of a major life activity must exist. Corrective actions may result in an impairment that does not qualify as a disability The dissents suggest that viewing individuals in their corrected state will exclude from the definition of “disab[led]” those who use prosthetic limbs, see post, at 3—4 (opinion of Stevens, J.), post, at 1 (opinion of Breyer, J.), or take medicine for epilepsy or high blood pressure, see post, at 14, 16 (opinion of Stevens, J.). This suggestion is incorrect. The use of a corrective device does not, by itself, relieve one’s disability. Rather, one has a disability under subsection A if, notwithstanding the use of a corrective device, that individual is substantially limited in a major life activity.

2. Sutton Decision: Agency Role No agency, however, has been given authority to issue regulations implementing the generally applicable provisions of the ADA, see §§12101—12102, which fall outside Titles I-V. Most notably, no agency has been delegated authority to interpret the term “disability.” §12102(2). Agencies have issued interpretive guidelines to aid in the implementation of their regulations. Although the parties dispute the persuasive force of these interpretive guidelines, we have no need in this case to decide what deference is due.

3. Sutton Decision: 43,00,000 figure and definition of a disability Regardless of its exact source, however, the 43 million figure reflects an understanding that those whose impairments are largely corrected by medication or other devices are not “disabled” within the meaning of the ADA. The estimate is consistent with the numbers produced by studies performed during this same time period that took a similar functional approach to determining disability. Because it is included in the ADA’s text, the finding that 43 million individuals are disabled gives content to the ADA’s terms, specifically the term “disability.” Had Congress intended to include all persons with corrected physical limitations among those covered by the Act, it undoubtedly would have cited a much higher number of disabled persons in the findings. That it did not is evidence that the ADA’s coverage is restricted to only those whose impairments are not mitigated by corrective measures.

4. The Report of the House Committee on Education and Labor : “[whether] a person has a disability should be assessed without regard to the availability of mitigating measures, such as reasonable accommodations or auxiliary aids.” The Report adds: “For example, a person who is hard of hearing is substantially limited in the major life activity of hearing, even though the loss may be corrected through the use of a hearing aid. Likewise, persons with impairments, such as epilepsy or diabetes, which substantially limit a major life activity are covered under the first prong of the definition of disability, even if the effects of the impairment are controlled by medication.”. All of the Reports are replete with references to the understanding that the Act’s protected class includes individuals with various medical conditions that ordinarily are perfectly “correctable” with medication or treatment. See id., at 74 (citing with approval Straithe v. Department of Transportation, 716 F.2d 227 (CA3 1983), which held that an individual with poor hearing was “handicapped” under the Rehabilitation Act even though his hearing could be corrected with a hearing aid Dissent: Legislative History at the Intent of the ADA

5. Dissent: Corrective State Consideration When an employer refuses to hire the individual “ because of ” his prosthesis, and the prosthesis in no way affects his ability to do the job, that employer has unquestionably discriminated against the individual in violation of the Act. If the Court is correct that “[a] ‘disability’ exists only where” a person’s “present” or “actual” condition is substantially impaired, ante, at 9—10, there would be no reason to include in the protected class those who were once disabled but who are now fully recovered. Subsection (B) of the Act’s definition, however, plainly covers a person who previously had a serious hearing impairment that has since been completely cured.

6. Dissent: General Reliance on Agency Guidelines Each of the three Executive agencies charged with implementing the Act has consistently interpreted the Act as mandating that the presence of disability turns on an individual’s uncorrected state. We have traditionally accorded respect to such views when, as here, the agencies “played a pivotal role in setting [the statutory] machinery in motion.” At the very least, these interpretations “constitute a body of experience and informed judgment to which [we] may properly resort” for additional guidance. Skidmore v. Swift & Co., 323 U.S. 134, 139—140 (1944). See also Bragdon, 524 U.S., at 642 (invoking this maxim with regard to the Equal Employment Opportunity Commission’s (EEOC) interpretation of the ADA).

7. The EEOC’s Interpretive Guidance provides that “[t]he determination of whether an individual is substantially limited in a major life activity must be made on a case by case basis, without regard to mitigating measures such as medicines, or assistive or prosthetic devices.” 29 CFR pt. 1630, App. §1630.2(j) (1998). The EEOC further explains: “[A]n individual who uses artificial legs would... be substantially limited in the major life activity of walking because the individual is unable to walk without the aid of prosthetic devices. Similarly, a diabetic who without insulin would lapse into a coma would be substantially limited because the individual cannot perform major life activities without the aid of medication.” The Department of Justice: “[t]he question of whether a person has a disability should be assessed without regard to the availability of mitigating measures, such as reasonable modification or auxiliary aids and services.” The Department of Transportation has issued a regulation adopting this same definition of “disability.” Dissent: Specific Agency Positions

8. Justice Rehnquist in Garcia v. United States, 469 U.S. 70 (1984): “In surveying legislative history we have repeatedly stated that the authoritative source for finding the Legislature’s intent lies in the Committee Reports on the bill, which ‘represen[t] the considered and collective understanding of those Congressmen involved in drafting and studying the proposed legislation.’ 469 U.S. 70 The Senate Report states that “whether a person has a disability should be assessed without regard to the availability of mitigating measures, such as reasonable accommodations or auxiliary aids.” “[A]n important goal of the third prong of the [disability] definition is to ensure that persons with medical conditions that are under control, and that therefore do not currently limit major life activities, are not discriminated against on the basis of their medical conditions. For example, individuals with controlled diabetes or epilepsy are often denied jobs for which they are qualified. Such denials are the result of negative attitudes and misinformation.” The Report of the House Committee on the Judiciary states, in discussing the first prong, that, when determining whether an individual’s impairment substantially limits a major life activity, “[t]he impairment should be assessed without considering whether mitigating measures, such as auxiliary aids or reasonable accommodations, would result in a less-than- substantial limitation.” The Report continues that “a person with epilepsy, an impairment which substantially limits a major life activity, is covered under this test,” as is a person with poor hearing, “even if the hearing loss is corrected by the use of a hearing aid.” Dissent: Legislative History Role and ADA Intent

9. Dissent: 43,000,000 Figure and ADA Intent When faced with classes of individuals or types of discrimination that fall outside the core prohibitions of anti-discrimination statutes, we have consistently construed those statutes to include comparable evils within their coverage, even when the particular evil at issue was beyond Congress’ immediate concern in passing the legislation. Congress, for instance, focused almost entirely on the problem of discrimination against African-Americans when it enacted Title VII of the Civil Rights Act of 1964 See, e.g., Steelworkers v. Weber, 443 U.S. 193, 202—203 (1979). But that narrow focus could not possibly justify a construction of the statute that excluded Hispanic-Americans or Asian-Americans from its protection—or as we later decided (ironically enough, by relying on legislative history and according “great deference” to the EEOC’s “interpretation”), Caucasians. See McDonald v. Santa Fe Trail Transp. Co., 427 U.S. 273, 279—280 (1976).

10. Dissent: 43,000,000 Figure and ADA Intent (cont.) What is more, in mining the depths of the history of the 43 million figure—surveying even agency reports that predate the drafting of any of this case’s controlling legislation—the Court fails to acknowledge that its narrow approach may have the perverse effect of denying coverage for a sizeable portion of the core group of 43 million. The Court appears to exclude from the Act’s protected class individuals with controllable conditions such as diabetes and severe hypertension that were expressly understood as substantially limiting impairments in the Act’s Committee Reports, and even, in the studies that produced the 43 million figure. Given the inability to make the 43 million figure fit any consistent method of interpreting the word “disabled,” it would be far wiser for the Court to follow—or at least to mention—the documents reflecting Congress’ contemporaneous understanding of the term: the Committee Reports on the actual legislation.

11. The definition of disability also requires that disabilities be evaluated “with respect to an individual” and be determined based on whether an impairment substantially limits the “major life activities of such individual.” §12102(2). Thus, whether a person has a disability under the ADA is an individualized inquiry The agency guidelines’ directive that persons be judged in their uncorrected or unmitigated state runs directly counter to the individualized inquiry mandated by the ADA. The agency approach would often require courts and employers to speculate about a person’s condition and would, in many cases, force them to make a disability determination based on general information about how an uncorrected impairment usually affects individuals, rather than on the individual’s actual condition. For instance, under this view, courts would almost certainly find all diabetics to be disabled, because if they failed to monitor their blood sugar levels and administer insulin, they would almost certainly be substantially limited in one or more major life activities. A diabetic whose illness does not impair his or her daily activities would therefore be considered disabled simply because he or she has diabetes. Thus, the guidelines approach would create a system in which persons often must be treated as members of a group of people with similar impairments, rather than as individuals. This is contrary to both the letter and the spirit of the ADA Sutton Decision: Individualized Inquiry of a Disability
